Does Fluttering Noise From Top Of Head Indicate Aneurysm?

Hi, may I answer your health queries right now ? Please type your query here... Hi last night I had like a fluttering noise that seemed to come from the top of my head and even my son that was standing next to me heard it. I cant get into my doctor till tomorrow but am very stressed thinking I may be having an aneurysm.
Should I go to a hospital or wait until tomorrow
